This is a closer shot showing the consolidation of concrete mentioned with the following photo. The largest "bughole" is no larger than a nickle at the surface and no deeper than 1/4". These "bugholes" are created by bleedwater or excess water that is forced out of the concrete and "puddles" against the form. Bugholes that are less than 1/4" deep and smaller than a quarter are considered to be of no consequence structurally. In an ICF wall, the appearance of the concrete is not an issue either.
